c# - Why Is XDocument.Descendants().Count() > 0 for an Empty Document? -

here's method:

var document = xdocument.parse(source); if (document.descendants().count() > 0) {     // code shouldn't execute } else {     // code should execute }

this code breaks when in 'document' variable:

<ipb></ipb>

since doesn't have descendants, why entering if conditional? shouldn't try load anything, yet , breaks when finds nothing scrape.

using breakpoints can confirm document variable has content posted above when breaks , enter if.

have tried using:

document.root.descendants().count() > 0;

the root element sits below xdocument.
